SPECIFICATION forming part of Letters PatentNo. 291,045, dated January1, 1884.

Application filed March 23, 1883. (No' model.) Patented in Germany May9, 1882, No.21,716; in England July 26, lFciliNu. 3,5 5;

To alt whom it may concern.-

Be it known that I, JOHN GJERS, a subject of the Queen of Great Britainand Ireland, re-

siding at Middlesbrough, in the North Riding of the county of York,Kingdom of Great Britain and Ireland, have invented new and usefulApparatus for Equalizing the Temperature of Steel Ingots, (for which,with other improvements, I have obtained a patent in Great Britain, No.3,545, bearing date July 26, 1882,) of which the following is aspecification.

My invention has reference to an arrangement of apparatus wherein steelingots can be treated in such a way that they may be converted into afinished or partly-finished state without reheating them in a furnace.

According to my present invention for this purpose, I employ chambersconstructed in a mass of brick-work after the manner of pigeonholes, sothat ingots may be treated therein in a horizontal position, and may,when ready,

pass out in the same horizontal attitude in which they are to be treatedby the rolls. Such an arrangement of apparatus is shown in theaccompanying sheet of drawings, in which- Figure 1 is a front view,partly in section, of my improved apparatus, Fig. 2, a crosssectionshowing one construction of pigeon .holes; and Fig. 3, a similar sectionshowing a second construction of pigeon-holes. These pigeon-holes orcells a may, as is evident, be arranged for the reception each of morethan one ingot, as shown. at the right-hand portion of Fig. 1, where twoingots are placed in one pigeon-hole or cell; but it is not usuallydesirable to arrange the pigeon hole or cell to contain more than oneingot. The bottom of each pigeon hole or cell contains a ledge orprojection, b, for the ingot to rest upon and to facilitate thecharging.

In the drawings I have shown seven pigeonholes or cells in a singlestructure or mass of brick-work, c but I need scarcely remark that anyother convenient number maybe employed. Doors or covers a are used toclose the mouths of the pigeon-holes or cells, and these doors or coversmay conveniently be hinged or jointed, as shown at f. The pigeon-hole orcell,as represented in Fig.- 2, extends throughout the whole width ofthe structure or mass of brickwork, and two doors or covers, 6, are usedto inclose the ingot or ingots-one at each end of the pigeon-hole orcell. In cases where the hole or cell extends only partly through themass of brick-work (illustrated in Fig. 3) only one door or cover,e, isrequired for each pigeonhole or cell. Into these pigeon-holes orhorizontal cells the ingots are charged in the man; ner usual forcharging ingots into ordinary heating-furnaces, a two-pronged tool beingused for charging the ingot, which, when (1eposited on the aforesaidledge b, will allow of the pronged tool being readily withdrawn.

It will be evident that cells or chambers in a mass of brick-work, asabove described, may

for Letters Patent of the United States filed by 0 me on the 23d day ofMarch, 1883, Serial No. 89,275, care being taken that the mouths of thepits shall be in positions clear of the supporting-girders.

I do not herein claim the process of equal- 7 5 izing the temperature ofsteel ingots, such having been made the subject of aseparateapplication, No. 58,689, filed by me April 18, 1882, nor theconstruction shown and described in my application, No. 89,280, filedMarch 23,

1888; but i What I do claim is- 1. An apparatus for equalizing thetemper ature of steel ingots, comprising a series of permanenthorizontal chambers resembling pigeon-holes formed in a mass ofbrick-work constructed to act as an accumulator of heat, and eachchamber being arranged to inclose an ingot (or ingots) and allow it (orthem) to soak, (with exclusion of air,) so as to attain o throughout asuitable temperature for rolling off successfully into blooms ordirectly into a finished article without reheating in a furnace,

substantially as described.

' ,2. In an apparatus for equalizing the temperature of steel ingots, aseries of horizontal chambers resembling pigeon-holes formed in andextending entirely through a mass of brickwork constructed to act as anaccumulator of heat, each of said chambers being provided at each endwith a removable cover, so that ingets may be inserted at one end, heinclosed in the chamber, (with exclusion of air,) so as to soak therein,and be afterward withdrawn at the other end of the chamber,substantially as described, for the purpose specified.

3. In an apparatus for equalizing the temperature of steel ingots, acell or chamber constructed in the manner of a pigeon-hole in a mass ofbrick-work designed to act as an accumulator of heat, said chamber beingprovided with a ledge or projection, b, for the ingot to rest upon andto facilitate the charging,

and also with a cover at each end, so arranged that an ingot may be fedin at one end, then incloscd within the chamber practically to theexclusion of air, and afterward may be withdrawn at the other end,substantially as described, for the purpose specified.

4. A horizontal chamber for equalizing the temperature of steel ingots,constructed to open at the end or ends, and not at the top,substantially as described.

JOHN GJERS.
